Superimposed-image display device

Abstract

Provided is a superimposed-image display device configured such that when there is a guidance divergence point, which is a guidance target, ahead in a traveling direction of a vehicle, a plurality of guidance objects that provide guidance on an entry route that enters the guidance divergence point and an exit route are displayed. When a course including the entry route, the guidance divergence point, and the exit route is displayed using a plurality of guidance objects, the plurality of guidance objects are displayed so as to match the elevation of the line of sight of an occupant and displayed so as to be shifted to locations that are on the opposite side to an exit direction at the guidance divergence point relative to the front of the vehicle.

What is claimed is: 
     
       1. A superimposed-image display device that is mounted on a vehicle and superimposes a guidance object on a view around the vehicle so that an occupant of the vehicle visually identifies the guidance object, the guidance object providing guidance on a course to the occupant, the superimposed-image display device comprising:
 object displaying means for displaying a plurality of guidance objects when there is a guidance divergence point ahead in a traveling direction of the vehicle, the guidance divergence point being a guidance target, and the plurality of guidance objects providing guidance on an entry route that enters the guidance divergence point and an exit route that exits from the guidance divergence point, 
 wherein 
 the object displaying means displays a course including the entry route, the guidance divergence point, and the exit route using the plurality of guidance objects, displays the plurality of guidance objects such that the plurality of guidance objects match an elevation of a line of sight of the occupant of the vehicle, and displays the plurality of guidance objects such that the plurality of guidance objects are shifted toward an opposite side to an exit direction at the guidance divergence point relative to front of the vehicle. 
 
     
     
       2. The superimposed-image display device according to  claim 1 , wherein
 the object display means
 displays, in the entry route, corresponding ones of the plurality of guidance objects at locations shifted by a certain distance from a center of the vehicle in a vehicle width direction, and 
 displays, in the exit route, corresponding ones of the plurality of guidance objects at locations shifted by a distance determined based on a number of lanes on the exit route from a center of a road on the exit route. 
 
 
     
     
       3. The superimposed-image display device according to  claim 2 , wherein
 the object displaying means
 displays, in the entry route, corresponding ones of the plurality of guidance objects at locations shifted by a distance corresponding to a half-lane from the front of the vehicle and the center of the vehicle in the vehicle width direction toward the opposite side to the exit direction, and 
 displays, in the exit route, corresponding ones of the plurality of guidance objects at locations shifted by a distance corresponding to a number of lanes on the course from the center of the road on the exit route toward a course side. 
 
 
     
     
       4. The superimposed-image display device according to  claim 3 , wherein the object displaying means sets a circle that touches two straight lines including an entry route straight line and an exit route straight line, and displays corresponding ones of the plurality of guidance objects side by side along the circle within the guidance divergence point, the entry route straight line being a straight line extending along the course on the entry route, and the exit route straight line being a straight line extending along the course on the exit route. 
     
     
       5. The superimposed-image display device according to  claim 3 , wherein the object displaying means performs a process with reference to links in map information, the process displaying the plurality of guidance objects such that the plurality of guidance objects are shifted to locations that are on the opposite side to the exit direction relative to the front of the vehicle. 
     
     
       6. The superimposed-image display device according to  claim 2 , wherein the object displaying means sets a circle that touches two straight lines including an entry route straight line and an exit route straight line, and displays corresponding ones of the plurality of guidance objects side by side along the circle within the guidance divergence point, the entry route straight line being a straight line extending along the course on the entry route, and the exit route straight line being a straight line extending along the course on the exit route. 
     
     
       7. The superimposed-image display device according to  claim 2 , wherein the object displaying means performs a process with reference to links in map information, the process displaying the plurality of guidance objects such that the plurality of guidance objects are shifted to locations that are on the opposite side to the exit direction relative to the front of the vehicle. 
     
     
       8. The superimposed-image display device according to  claim 1 , wherein the object displaying means sets a circle that touches two straight lines including an entry route straight line and an exit route straight line, and displays corresponding ones of the plurality of guidance objects side by side along the circle within the guidance divergence point, the entry route straight line being a straight line extending along the course on the entry route, and the exit route straight line being a straight line extending along the course on the exit route. 
     
     
       9. The superimposed-image display device according to  claim 8 , wherein the object displaying means performs a process with reference to links in map information, the process displaying the plurality of guidance objects such that the plurality of guidance objects are shifted to locations that are on the opposite side to the exit direction relative to the front of the vehicle. 
     
     
       10. The superimposed-image display device according to  claim 1 , wherein the object displaying means performs a process with reference to links in map information, the process displaying the plurality of guidance objects such that the plurality of guidance objects are shifted to locations that are on the opposite side to the exit direction relative to the front of the vehicle.
